On the web, I see no downvote buttons on posts. In third party apps, downvoting does nothing. This affects all instances.

Comments are not affected, just posts.

Any idea what causes this?

Downvotes are kind of a drag anyway. Can you still upvote?

It affects the ones that allow downvoting.

Sure, but the behavior seems like a bug or misconfiguration.

They can be, but they also help curate things worth spending time on when you only have a few minutes to kill.

I cannot find any reason for this, your account is in good standing and none of the automated downvote blocks should be applying to you.

Thanks for looking into it. Anything to do other than delete the account and try again? This is the second account that had an issue but not the same issue.

I used my l33t hax0r skills to log in as you and there were downvote buttons everywhere there should be. I downvoted a post, too.

Sorry, I'm out of ideas. Must be something with your browser.
